Abstract
The results of numerical simulation of operation of an aerosol lidar with two receiving channels for study the effect of amplification of radiation power backscattered in the atmosphere are presented. Simulation was performed with consideration for location of one of the receivers apart from the probing beam axis. Requirements on the parameters of the lidar transceiver and probing path geometry for sufficient registration of the backscattered radiation power amplification effect were defined. It is shown that for path length more than 1 km and small receiving apertures the amplification coefficient for the backscattered radiation power can exceed 1.4.
